FROM THE TRIASSIC CONGLOMERATE OF SOUTH WALES. 515 
Emu, that, leaving all other considerations out of the question, one 
would not feel much hesitation in declaring for the Avian and, 
indeed, Ratitous character of the animal which produced the former. 
But the other considerations are too important to be overlooked. 
Although the remains of fossil vertebrates have in several instances 
been discovered in the Triassic deposits of 8.W. England, yet none 
have hitherto been referred or referable to Birds; on the other 
hand many of them are true Reptiles, though with extraordinarily 
strong ornithic affinities. The existence of Dinosaurs during the 
Trias gives, indeed, a strong primd facie probability to the supposition 
that these associated bird-like footprints were really produced by 
some form of Ornithic Reptile. 
The occurrence of Thecodontosaurus and Palcosaurus in the 
magnesian conglomerate of Durdham Down, Bristol, which is on 
the same parallel of latitude as Newton Nottage, and only 45 miles 
distant, is very suggestive; and I cannot help thinking that one or 
other of the animals which possessed the bones must have been a 
near relation to that which has left its footprints in the magnesian 
conglomerate of 8. Wales. 
A comparison of these footprints with those figured by Hitchcock 
shows that they must be referred to the genus Brontozoum, of which 
they will form a new species, which I propose to call Brontozoum 
Thomasi, in honour of its discoverer.

These beds are mapped by the Geological Survey as dolomitic 
conglomerate and marlstones, and appear to lie in a depression of 
the Carboniferous Limestone, by which they are bounded on all sides 
except the W., where they dip gradually into the sea. Imme- 
diately behind the village of Newton on the N. they are deposited 
close up to the base of the Limestone cliff, on which most of the 
village is built; and they are shown all along the road to Nottage 
at intervals, forming a sort of natural pitching for the road. At 
Schorlon, where this stone was dug up, I was unable to examine 
them on account of the snow ; but in the small exposures I saw they 
seem to dip very slightly, perhaps 2 or 3 degrees W. As it was 
useless, on account of the weather, to attempt any thing more here, 
I proceeded to Porth-Cawl, and striking W. along the shore found that 
the Carboniferous beds still maintained the same general characters 
as at Newton, and had a slight dip W.N.W. of about 8 degrees. 
About ? of a mile past the Rest, a fault about 25 to 30 yards in 
width occurs, in which the Limestone-beds are thrown nearly 
vertical and considerably crushed. The conglomerate comes in here 
right up to the edge of the fault, and is nearly horizontal at the 
point of junction, but increases in dip gradually as it extends west- 
wards till it passes under the channel and blown sands at a 
general dip of about 10 degrees. I examined bed after bed as I 
walked along the shore with the hope of meeting one of something 
like the same texture as the stone, or to try for any signs of other
